TRANSOM SIDE BEARING.

SPECIFICATION forming part of Letters Patent No. 754,979, dated March22, 1904.

Application filed May 4, 1903. Serial No. 155,496. (No model.)

To all whont it may concern:

Be it known that I, MAX Donn, a citizen of the United States, residingat the city of St. Louis, State of Missouri,have invented a certain newand useful Improvement in Transom Side Bearings, of which the followingis a specification.

My invention relates to a new and useful improvement in transom sidebearings, and

has for its object to provide a transom side bearing which will bedurable and efficient and which may be adjusted to any transom of a carregardless of the angle with the horizontal of that portion of thetransom-to which the side bearing is attached, and thus save the cost ofmaking patterns for a new transom side bearing every time the angle ofthis portion of the transom is changed.

With these ends in view this invention consists in the details ofconstruction and combination of elements hereinafter set forth and is asection of car and truck with side bearing in place. Fig. 4 is a planview of same with car-floor removed.

1 is the body-bolster or transom of the car.

2 is the truck-bolster of the car and has nothing to do with myinvention, but merely shows the relative position of the parts.

3 is the truck side bearing and has nothing to do with my invention, butmerely shows the relative position of the parts.

Transom side bearings are usually in one piece; but my invention showsit in two parts. The upper part4: is fastened to the transom rigidly bymeans of the bolts 5, which are countersunk into the lower part of thesaid part 4. Thelower surface of part 4 represents an arc or circularsurface, which rests on a corre-' sponding arc-surface, as shown indrawings in part 6, or the lower half of said transom side bearlng,whlch is held in place by being swung or pivoted to part 4: by means ofthe bolts 7 Thus the lower part of the said transom side bearing is heldrigidly in place by the pivotal bolts 7, and thus the sidebearing may bead- 1 justed to any transom, whatever the angle of said transom 1 maybe, and disposes with the necessity of providing new patterns every timethe angle of the transom is different. The bolts 7 carry no strain; butthe strain is taken up on the circular surfaces.

It is not intended, neither is it possible, for the curved surfaces toact as a pivot for the bearing, as all the strains act toward the centerof the arc of the curved surface, their only use being to adjust thebearing to fit any transom. I

Having thus described the invention, what I claim is 1. The combinationin a transom side bearing of two parts, one above the other, the lowerpart being attached to the upper part so as to rest rigidly on circularor arc surfaces by means of bolts so as to be adjustable to any transomregardless of the angle with the horizontal of that portion of thetransom to which the side bearing is attached, and thus avoid having newpatterns made for every transom with different angle.

2. The combination of a transom side hearing in two pieces the lowerpartbeing fastened to the upper part so as to rest rigidly on circularor are surfaces by means of bolts so as to be adjustable to any transomregardless of the angle with the horizontal of that portion of thetransom to which the side bearing is attached and means for placing thestrain on circular surfaces,all substantially as set forth.

In testimony whereof I have hereunto afiixed my signature in thepresence of two subscribing witnesses.

MAX DORN.
